About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX80-30
The AirTAC SAIJ160X80-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty operations. With a 160 mm bore, it generates 10053 N of pull force at 0.5 MPa. The integrated adjustment screw allows you to trim the effective travel back by up to 30 mm, creating a precise 50-80 mm usable stroke window without swapping out the hardware.
This unit features a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Operating at speeds of 30-500 mm/s, it relies on variable air cushions at both ends to decelerate the heavy 40 mm rod smoothly.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX80-30 Is Used
Heavy Press Tuning
Dial in the exact 50-80 mm end-stop during heavy press commissioning to accommodate material thickness variations without adding external stopper blocks.
Product Changeover
Quickly adjust the rear stroke screw on a production line when switching to a different product size, saving downtime on machinery reconfiguration.
High-Force Positioning
Leverage the 10053 N pull force to move heavy jigs into place, using the adjuster to set the precise retraction point for delicate alignment tasks.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX80-30 the Right Cylinder?
Selecting this 160 mm bore cylinder makes sense when your application requires extreme force, such as 14074 N push at 0.7 MPa, alongside precise end-position tuning. If you need less force, stepping down to a 125 mm bore yields 6136 N push at 0.5 MPa. Choose this adjustable-stroke SAIJ over a fixed SAI when your machine setup requires product changeovers or commissioning fine-tuning within that 50-80 mm travel window. It supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
Remember that the rear adjuster functions strictly as a travel stop, not a locking device; it cannot hold a load without continuous live air pressure. For positive load-holding on heavy machinery, consider an external rod lock or pilot-operated check valve. When matching ISO 15552 replacements, verify the 80 mm stroke, 30 mm adjustment, PT G3/4 ports, and the absence of a magnet (-S).

- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ160 Adjustable Cylinder SAIJ160AX80-30 FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of pull force and 14074 N of push force. At the maximum 1.0 MPa pressure, it achieves a push force of 20000 N.
The rear adjusting screw acts as a mechanical stopper that lets you shorten the 80 mm nominal stroke by up to 30 mm, providing an adjustable travel window between 50 and 80 mm. It sets the end position but does not lock the load without live air.
